Hundens parvovirus : patologi och riskfaktorer

Canine parvovirus is associated with two disorders: enteritis, which is common, and myocarditis, which is rare. Prominent clinical signs of parvovirus enteritis are vomiting, diarrhea and rapid dehydration. Canine parvovirus type 2 (CPV-2) is very contagious. When CPV-2 first emerged it had high rates of mortality, but later studies have shown that most infections are self-limiting and do not require veterinary care. Mortality rates vary greatly, and therefore it is important to determine risk factors for developing severe canine parvovirus enteritis.

Kungliga blodsugare och markattor : En genusstudie av politiska brott på 1700-talet

The purpose of this study is to examine political crimes in and women?s political activity in 18th century Sweden. The cases of political crimes which has been used range from 1700- 1789 and they form an outline of the patterns of political crime in this century. These cases contain different types of political crimes, but most common ar defamation of the royal family, defamatory writings, rumor-spreading and treason. To study women?s political activity, seven cases ranging from 1749 to 1758 have been more closely studied.

Prevalens och genetisk karaktärisering av afrikansk svinpestvirus i vektorer och tamsvin i Uganda

African swine fever, ASF, was first described 1921, in Kenya. The virus has thereafter spread through many African countries as well as in Europe, Asia, South- and Central America. The virus is spread via three different cycles, of which one is sylvatic and includes warthogs and soft ticks. The other two are between domestic pigs and the one most common one is caused by humans, who not always realize the seriousness of precautions. The infection manifests as hemorrhagic fever, but can also be more or less unnoticed. The aim of this study was to use molecular tools to detect and partly genetically characterize ASFV both in soft ticks and in serum from domestic pigs in Uganda. Comparing viruses detected in ticks with those detected in domestic pigs I also wanted to investigate possible links between the sylvatic and domestic cycle.

Gage R&R studie på mätutrustning för förpackningsavstånd

The aim of the thesis is to analyse and understand resolution, repeatability and reproducibility of the measurement system for package distance. The measurement system for package distance is already in use, no Gage R&R has been performed on the system and before spreading use of the system the quality of the system has to be understood and approved.

Lungmask och löpmagsnematod hos nötkreatur

Infection with intestinal parasites can in many cases be the reason for decreased performance or production. The gastro-intestinal nematode, Ostertagia ostertagi, and the lungworm, Dictyocaulus viviparus, are the most pathogenic nematodes of cattle and severe infection can lead to death. They have both a direct lifecycle and on the pasture the parasites spread as freeliving worms. The parasites are mainly a problem for the first season grazers. They have not developed immunity against the parasites and are therefor more sensitive to parasite infections.

Rotavirus zoonotiska potential : kan infekterade föl smitta människa?

Rotavirus causes diarrhea in young mammals all over the world, including infant humans. The diarrhea leads to severe dehydration that can be fatal if left untreated. The dehydration can be treated with fluid therapy and the infection heals itself. Despite the relatively easy treatment half a million children under the age of five dies every year due to diarrhea caused by rotavirus. Rotavirus sorts into the family Reoviridae and is a double-stranded RNA virus with a segmented genome.

Klamydiainfektioner i Sverige  : Kan en geografisk analys förklara det rumsliga mönstret?

Chlamydia is a sexually transmitted infection. The infection rates have increased in the last decade. During 2008 the trend rates declined in all counties and regions in Sweden. Chlamydia infections have a geographical spatial pattern differences. This is seen from the national surveillance data report from the Swedish Institute for infectious disease control (SMI).

Användning av rötrest från kombinerad etanol och biogasproduktion : en jämförelse mellan tre alternativ

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

Stump treatment with the root rot antagonist phlebiopsis gigantea : - sensitivity of P. gigantea spores to high pressure stress; - reduced water consumption for stump treatment

Stump treatment today requires large quantities of clean water mixed with the protective product Rotstop, to fully cover the stump surface. In order to reduce the water consumption without reducing the coverage of the stump surface, the pressure in the stump treatment device can be increased. Therefore, the Phlebiopsis gigantea (Fr.) Jül. suspension used as a biological control agent to prevent Heterobasidion annosum (Fr.) Bref. infection was pressure-tested.

Inventering av förorenade områden enligt MIFO-fas 1 : Erasteel Kloster AB, Söderfors

Erasteel Kloster AB Söderfors have been commissioned by the county administrative board in Uppsala län to make an inventory of possible contaminations in theirs industrial- and landfill areas on the basis of the Swedish Environmental Protection Agency?s; ?Method of Surveying Contaminated Sites-phase 1? (MIFO-fas 1). The inventory starts with maps and archive studies, place visits and interviews, and finally a risk classification is done. A risk classification is a compilation of four categories; pollutant toxicity, contamination level, possible spreading condition of the pollutant, sensitivity and protection value of the environment. In this paper five partial areas (Holmen- and Jörsöområdet, Järnsvampsområdet, Ingsådeponin, Östra verken and Myrområdet) have been described from a historical point of view. Only parts of four areas have been risk classified (Holmen- and Jörsöområdet, Järnsvampsområdet, Ingsådeponin and Östra verken), due to that the other areas isn?t own by Erasteel Kloster AB. Holmen- and Jörsöområdet Holmen- and Jörsöområdet have during the entire activity time been carried out as the production core in the company.

Mellanchefens dilemma : En fallstudie gjord på Skattekontoret i Örebro

In large organizations one can often find middle managers at several different levels within a company. Middle managers regularly experience their positions as complicated as they have both superiors as well as subordinates? to please. We have chosen to refer to this problem as ?the middle-management dilemma?.

Vaccination mot Humant Papillomvirus - vem bör vaccineras?

Background: Infection with Human Papillomavirus, HPV, is one of the world's most common sexual transmitted infections. The virus causes genital warts (condyloma) but certain virus types can cause cancer. The most common cancer type caused by the virus is cancer of the cervix. Nowadays there is a screening program for women between 23 and 60 years of age where Pap smears of the cervix is taken to discover abnormalities at an early stage. Cervical cancer is very common all over the world and this screening program saves many lives, but not in the less developed countries since the screening program is too expensive.

Development of new food products with components active against Helicobacter pylori - with purpose to improve gastric health in humans

Gastric and intestinal disorders are common and costly human health problems worldwide. Helicobacter pylori are a gram-negative, pathogen bacteria and the most common cause of duodenal and gastric ulcer in the stomach the intestinal mucosa. Prolonged infection and colonization can lead to chronic gastritis and stomach cancer. H. pylori are present in the gastric and intestinal mucosa of half of the world population and a relation between infection and low socioeconomic status has been shown.
